UNC Standard Industrial Kits

Chrislynn Repair Kits contain everything needed to complete your repair job except a drill bit. This includes a high-speed steel STI plug tap, a combination installation/tang break off tool, and a generous quantity of inserts, in a length equal to one and a half times the diameter of the insert. These kits are available in metric sizes from M2 to M64, and in American sizes from 2-56 to 1-1/2”. Larger “8-Pitch” sizes up to 3-1/2” are available here.
